Answer:
2 seconds
Explanation:
if a ball travels 1/2 meter per second, and there's 2 halfs in a whole, 1/2 meter per second x 2 halfs in a whole meter is 2 seconds to travel a meter
The insulin levels lead to the cause of type 2 diabetes
relation between potential difference and electric field is given as
![E . d = \Delta V](https://tex.z-dn.net/?f=E%20.%20d%20%3D%20%5CDelta%20V)
so here we know that
d = 3 cm
![\Delta V = 30 V](https://tex.z-dn.net/?f=%5CDelta%20V%20%3D%2030%20V)
![E \times 0.03 = 30](https://tex.z-dn.net/?f=E%20%5Ctimes%200.03%20%3D%2030)
![E = 1000 N/C](https://tex.z-dn.net/?f=E%20%3D%201000%20N%2FC)
So now when plates are separated to 4 cm distance carefully
the potential difference between them will change but the electric field between them will remain constant
So at distance of 4 cm also the electric field will be E = 1000 N/C
